ATTENTION!
Danger when touching live parts!
If the extension cable is damaged, remove
the plug from the outlet immediately! It
is recommended to connect the device
through a residual current device that oper-
ates at a rated leakage current <30 mA.
DANGEROUS!
Electric shock!
If the plug is cut off, the moisture can pen-
etrate through the mains cable and cause a
short circuit.
ASSEMBLY
1. Screw the L-shaped connecting corner
with the O-ring sealant onto the pump
outlet.
2. Insert the Universal Nipple with the O-ring
sealant into the L-shaped connecting cor-
ner.
3. Secure the hose (or pipe) to the Universal
Nipple.
4. Fasten the Float Switch Vertical on the
worm hose pipe using the mounting kit
(clamp) supplied with the pump
Fastening of the float switch vertical on the
hose pipe allows setting the pump on and
off levels depending on the chosen applica-
tion point of the pump:
■
The maximum working range of the float
switch is 160 mm. However, the interval
between pump on and off marks can be
reduced by rotating the stopper. Example:
The minimum level of sensor operation
can be claimed when using the pump as
a drainage in rooms without a pit.
■
The level sensor is mounted on the pres-
sure pipe using the mounting kit supplied
with the pump. To secure the sensor, it is
necessary to securely fasten the mount-
ing plate to the pipe using a worm hose
clamp, as shown in Fig. 1 and 2.

ATTENTION!
Fastening of the plate to the flexible hose
pipe is not permissible. If a flexible hose
pipe is used, the float must be attached to
the pump handle!
The design of the pump allows you to
change the pump on and off level relative
to its suction port. Limits of regulation are
about 300mm
Example: The minimum level of sensor oper-
ation can be claimed when using the pump
as a drainage pump. Maximum - when us-
ing a pump to feed water from the well.
The minimum pump shutdown level must
be at least 120 mm (from the bottom of the
pump).
